bonobo-storage — Abstract implementation of the Bonobo::Storage interface

## Synopsis

    void                bonobo_storage_copy_to              (Bonobo_Storage src,
                                                             Bonobo_Storage dest,
                                                             CORBA_Environment *ev);

## Description

The BonoboStorage C interface is extremely simple, this is since the CORBA client interface is where the action occurs. It is anticipated that relatively few people need to implement the Bonobo/Storage IDL interface.

The common entry point for BonoboStorage is that of opening a storage using the bonobo_storage_open function, perhaps by a container to use to persist a compound document:

## Details

### bonobo_storage_copy_to ()

    void                bonobo_storage_copy_to              (Bonobo_Storage src,
                                                             Bonobo_Storage dest,
                                                             CORBA_Environment *ev);

Implements a pure CORBA method for copying one storage into another, this is used by several BonoboStorage implemetations where a fast case localy copy cannot work.

`src` : | the source storage
`dest` : | the destination storage
`ev` : | CORBA exception environment
